Java

public RemapIntensityCommand( 
   RemapIntensityCommandFlags flags, 
   int[] lookupTable 
)

Public Function New( _ 
   ByVal flags As RemapIntensityCommandFlags, _ 
   ByVal lookupTable() As Integer _ 
)

- (instancetype)initWithFlags:(LTRemapIntensityCommandFlags)flags 
                  lookUpTable:(const int *)lookUpTable 
            lookUpTableLength:(NSUInteger)lookUpTableLength

public RemapIntensityCommand( 
   int flags,  
   int[] lookupTable 
)

public: 
RemapIntensityCommand(  
   RemapIntensityCommandFlags flags, 
   array<int>^ lookupTable 
)

Parameters

flags
Determines the color channel that will be used. For more information, refer to RasterColorChannel.

lookupTable
Table of integers containing lookup values.

Example

Run the RemapIntensityCommand on an image.
